[/l'lI/IIIIIIIIIIIIIA 7mm Inzrenfov- Patented Jan. 6, I942 "UNITED STATES PATENT. -OFFIC E 1 y p f-fazsazsw I DUPLEX CONCEAYLEDHINGIE j .Otto c. Gessler, Detroit, Mich. Application May 27, 194o,'seria 1 No. 337,393 3 Claims. (01.16-135) v My invention relates'to door hinges, and its principal object is to provide a hinge suitable for application more particularly to' automobile doors. The chief diificulty in this application results from the under-turn or inward curvature of the door due to the fact that the'body is nar rower at the sill than at the upper portion, so that while the upper hinge, when of ordinary construction, might be flushwith the body, the lower hinge would necessarily project to a considerable distance outwardly of the same when the door is in the closed position.

According to my invention I have provided a special construction in which the upper hinge and also the lower hinge may be flush with the body when the door is in the closed position.

A further object of my said invention is to provide a hinge of the character described which, being constructed from sheet metal, may be so standardized as to be capable of production in large quantities by modern production methods and which may be applied'to cars of widely varying design without the necessity of skilled labor for its installation and adjustment.

With these and other objects in view, I will now describe .a preferred embodiment of my invention with reference to the accompanying drawing, in which- Figure 1 is an elevation of my improved hinge, looking from the pillar r stationary end showing the parts in the relative positions which they occupy when the door is closed.

Figure 2 is a side elevation of the same looking from the left hand of Figure 1.

Figure 3 is a side elevation looking from the right hand of Figure 1.

Figure 4 is an elevational plan view.

Figure 5 is a sectional plan view taken on line 5-5 of Figure 1.

Figure 6 is a vertical section taken on the centerline of the hinge pin and looking in the direction of line 66 of Figure 1.

Figure 7 is a vertical section similar to Figure 6 but showing an alternative construction of the hing pin.

Figure 8 is a sectional plan view corresponding to Figure 5 but showing the parts in the relative positions which they occupy when the door is open.

Like characters designate corresponding parts throughout the several views. v

Referring more particularly to Figures 1 to 6 of the drawing, A is the stationary or pillar member of the hinge and B is the moving member the door. The member B, as shown more clearly in the section Figure 5, is made from two pieces of'sheet metalB', B2 folded upon one another to form a flange F for attachment to the door, an arcuate hook. H, and an eye E, the two pieces being joined together by welding as at W so as to ,forman openingffor reception of the hinge pin P. Themember A is also made .up from two pieces of sheet metal A, A2 folded'upon one another to form a; 'fiangefF' for attachmentto the pillar, and an arcuate housing K adapted to surround and support the hinge pin P, the parts A, A2 being joined together by welding as at W.

The pin P is surmounted by a head P2 and its middle portion is provided with arcuate grooves or cannelures P into which are pressed adjacent portions E of the eye so as to form a permanent assembly. Upon the outer ends of the pin P where they project from the eye are rotatably mounted a pair of collars C having arcuate grooves C into which are pressed adjacent porthe door. The flange F has a central gap G a through which the hook H of the movable member swings freely, the said flange being also provided with openings 0 for the securing bolts.

In the section, Figure '7, is shown a modification in which the hinge pin P is omitted and instead a pair of cylindrical hinge members E2 are formed in one piece with the eye E. These 85 members have annular grooves of arcuate shape E3 into which portions K of the housing K are pressed so as to form an eflicient hinge assembly of much simpler construction than that shown in Figure 6.

It will be observed from the foregoing description and by reference to the drawing that I have provided an exceedingly simple form of hinge and one which can be produced very cheaply, andwhile I have herein shown and described a preferred embodiment of my invention, it will be readily understood by those skilled in the art to which the sam pertains that various changes and modifications may be made to suit any particular or peculiar requirements without departing from the spirit of my invention as defined in i the appended claims. For example, while I have herein shown the fixed and movable portions as formed from two separate pieces connected by welding, it is contemplated that when constructof the same which is attached to the edge of ing th hinge from relatively light gauge sections of steel, the entire fixed portion and also the movable portion may each be pressed up from a single piece of metal bent by means of two or more press operations into the desired shapes so as to form a strong, rigid, and permanent assembly.

Having thus described my said invention, what I claim and desire to secure by Letters Patent of the United States is:

1. A hinge for doors comprising a stationary member having a substantially cylindrical housing including'a pair of hinge knuckles spaced apart to provide an opening therebetween and having a pair of overlapping flanges for attachment to a support; a hook-shaped movable member having a flange for attachment to a door and terminating in an eye adapted to fit between said knuckles; and a pintle pin passing through said eye and said knuckles so as to retain them in cooperative relation, said pin having a pair of annular grooves into which the material of said eye is pressed to form apermanent assembly and having projecting ends pivotally engaging said knuckles, the inner'wall of said eye surrounding said pin between said grooves being extended outwardly from said pin whereby to provide a chamber adjacent said pin.

2. A hinge for doors comprising a stationary member having a substantially cylindrical housing including a pair of hinge knuckles spaced apart to provide an opening therebetween and having a pair of overlapping flanges for attachment to a support; a hook-shaped movable member having a flange for attachment to a door and terminating in an eye adapted to fit between said knuckles; and a pintle pin passing through said eye and said knuckles so as to retain them in cooperative relation, said pin having projecting ends pivotally engaging said knuckles, there being separate bushings within said knuckles having cylindrical bores for receiving said ends and having external grooves into which the material of said knuckles is pressed to maintain said bushings in place.

3. A hinge'for doors comprising a stationary member having a substantially cylindrical housing including a pair of hinge knuckles spaced apart to provide an opening therebetween and having a pair of overlapping flanges for attachment to a support; a hook-shaped movable member having a flange for attachment to a door and terminating in an eye adapted to fit between said knuckles; and a pintle pin passing through said eye and said knuckles so as to retain them in cooperative relation, said pin having projecting ends pivotally engaging said knuckles, there being separate bushings within said knuckles having cylindrical bores for receiving said ends and having arcuate external grooves into which the material of said knuckles is pressed to maintain said bushings in place.
